Oxidation

I. cellular Respiration A. How Cells Acquire ATP 1. Cellular outside(a) respiration: Includes the various metabolic pathways that break down carbohydrates to set up ATP. a. Cellular respiration requires oxygen (aerobic process) and gives off carbon dioxide. 2. C6H12O6 + 6O2?6CO2 + 6H2O + efficiency 3. Glucose is oxidate and oxygen is reduced. a. oxidation is loss of negatrons and reduction is suck in of electrons. 4. A hydrogen atom consists of a hydrogen ion prescribed an electron (H+ + e-). So, when hydrogen atoms atomic number 18 removed from glucose, so are electrons. 5. Glucose is a high- muscularity molecule, carbon dioxide and water are low zip molecules. This process is exergonic and drives ATP synthesis which is an endergonic reaction. 6. The pathways of cellular respiration on the wholeow the skill within a glucose molecule to be released lessen so that ATP can be produced gradu aloney. 7. Cells would lose a lot of ener gy as heat if glucose breakdown occurred all at once. 8. Breakdown of glucose yields synthesis of 36 or 38 ATP (equivalent to about 39% of the energy that was available in glucose). B. NAD+ and hysteria 1. Each metabolic reaction in cellular respiration is catalyzed by its own enzyme. 2. NAD+ and cultus: Coenzymes of redox. 3.

As a metabolite is oxidized, NAD+ accepts 2 electrons and a H+ ion. This makes NADH. 4. electrons received by NAD+ and FAD are high- energy electrons and are usually carried to the electron transport system. 5. NAD+ is a coenzyme of oxidation-reduction since it some(prenominal) accepts and gives up electrons. 6. FAD is another coenz yme of oxidation-reduction that can replace ! NAD+. FAD accepts 2 electrons and both H+ ions to become FADH2. Cells need a limited means of these coenzymes because they constantly recycle. 7. The oxidation of glucose by removal of hydrogen atoms involves endovenous feeding phases: a. Glycolysis b. Preparatory (Prep) Reaction c. Citric Acid bout d. Electron Transport Chain...If you want to get a effective essay, coiffure it on our website: OrderEssay.net
